I have an outdoor iron rocking bench that I'm looking to get repainted. Unfortunately, it is so rusty that I'm thinking sandblasting the rust (and old-fashioned paint) off is the route to go (at smallest for preparing the chair for current paint). How much should it cost? Where would I get it done? Are in attendance sandblasing specialists?

The chair is adjectives iron, approx. 4'x4'x4'
My furnace blower kick on once the burners...
Answers:    You might inquire at an automotive body shop,one that paints cars,as they most likely own a sandblaster.
At the most you will pay the hourly shop rate or conceivably one of the guys will do it on the side(after work,of course) and save you a few bucks
Can I use caulk instead of plumbers putty?
There are places that specialize contained by wrought iron painting; check the wan pages and telephone and get 3 estimates. And ye they use sand blasting..
